Rhino releases on June 25th a box set containing re-mastered versions of Joni Mitchell’s first four Reprise albums (1968-71). The date is the 3 days after the 50th anniversary of the original release of Blue, which many fans consider a pivotal album in her recording career and one of the most thoughtful musical expressions of love lost ever. It was also her final Reprise release. Blue, like albums by Nick Drake and a few others from that era continue to be rediscovered by succeeding generations of fans and musicians alike.
